HOISTING-TRUCK.

To all lwhom t may concern Be it known that I, VICTOR E. BEAGLE, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Hoisting- Trucks, of which the following is a specification.

The invention hasfor an important obj ect to provide a truck adjustable to embrace articles of various sizes and shapes, with hoisting means engageable with such objects as the truck may be adjusted to.

It is an important object to improve the mannerof lifting heavy objects upon small trucks or large trucks, the device being readily applicable to use for handling both large and small articles.

A further aim is to give an improved construction in the framing of a truck.

Another purpose is to provide means to enable the adjustment'of lifting elements on a truck to engage an article in the most advantageous way, with respect to positioning the lifting elements relatively to the center of specific gravity of the object to be lifted, or to engage the objects at points least liable to damage by reason of its weight, abrasion, or othewise.

Additional objects, advantages and features of invention will be apparent from the construction, arrangement and combination of parts herein after described and shown in the drawings, where,

Figure 1 is a plan view of a truck constructed in accordance with my invention, Fig.- 2 is a side elevation thereof, Fig. 3 is a cross section ofl one of the sides of frame showing the construction of one of the jacks, and its mounting on the frame, Fig. 4 is an inner sideelevation of one of the jack elements, Fig. 5 is a detail of the tongue element of the truck, Fig. 6 is a side. elevation of a modification, Fig. 7 is a fragmentary plan view of a further modified construction of the frame, wherein the pivotal connections between the frame element are obviated, Fig. 8 is a detail elevation of one form of jack especially desirable for use with this invention, Fig. 9 is a detail of the mounting and adjusting means for the last named jack, Fig. 10 is' a cross sectional view of a truck frame equipped with jacks of the last mentioned type, illustrating one manner of use thereof, Fig. 11 is a detail of the mounting for such a jack upon an I beam.

There is illustrated a'truck comprising in Figs. 1 to 6 a frame including a transverse lhead piece 11, centrally of which there is fixed a Wear plate 12, upon which is pivoted the yoke 13 having the enlarged head port1on 14 of circular form seated snugly Vagainst the plate, a wheel 15 being revolubly specification of Letters Patent. Patented June 13, 1916, Application led May 15, 1915. Serial No. 28,370. i

spective side pieces 19, shown as formedof channel iron, and comprising the sides proper of the frame 10. Fixed upon the rear end portion of theseside members 19 there are casters 20, of any suitable construction, andif desired an additional caster maybe mounted at the forward part of these side members.

The plate 12 is extended rearwardly within the frame and provided with a downward extension 21, formed with a suitable channel on its inner side receiving slidably a jack foot piece 22, for vertical sliding movement, this foot piece being provided with a vertical Worm shank 23, engaged in a suitable nut 24 engaged upon the upper part of the extension formed with a beveled gear face with which there is meshed a corresponding gear 25 revolubly mounted on the side of an upperward extension 26 from the plate 12.V Commonly pivoted on the axis `of the gear 25 there is a lever 27, having a reversible pawl 28 thereon, arranged to engage peripheral teeth on the gear 25 under movement of the lever in one direction,

whereby the jack device may be operated by channel opening through its bottom end. The vertical portion 1s formed with a short upward-extension32 directly over-the channel 31, to receivethe worm shank 33of a jack foot 34 vertically movable in the chan- 32 upon which there is revolublyf' mounted a4v gear 38 meshed with the gear 35,

a lever 39 being pivoted gonfthe outerv part of the shaft provided with a pawl 40 arranged to engage peripheral teeth on the gear 38ofor its operation, inthe manner well understood in such jacks. The jack base is formed with integral outwardly extended portions`41, arranged to embrace the channel irons of the si e members snugly, having inturned portions 42 engaging -around the edges of the channel iron'whereby the 'ack bases are held snugly upon the side mem ers for sliding movement. If desired a set screw or other means may be provided as at 43 to hold the jack bases against sliding move-- ment on the side members of the frame 10. The number of gack elements on the side members of the rame may vbe increased to any extent found desirable.4 The rear ends of the side'members are adjustabl'y connected together by means of a chain`54 or other connecting member, the-chain being releasable at one side atleast, and any suit-4 able means provided whereby the chain may be let out to connect the side members at various distances apart.

In the hollow shank 17 of the front steering yforks 16, a bar 44`is inserted, having 'its inner end shaped like that of the usual pinch bar, and being releasably secured in the shank 17 by means 0f a pin 4,5 removably inserted through suitable apertures in the shank and the bar. f

Various forms of jack constructions mayl be employed other than that described, and I do not regard the invention as limited to the exact structure of any of the arts set forth. Thus, it may be found desirable to construct the side members of the frame as indicated in Fig. 7, where the front wheel and the yoke 13 by which i-t is carried are mounted on a body structure 46, having a transverse passage therethrough and provided with a clamping bolt 47 arranged to be projected into the passage, from above. The side elements 47 each comprise right angular pieces of suitable material havinga short forward arm 47 engaged slidably through the passage in the member 46, the

parts 47 of opposite side pieces'being aro inFig. 1. nel 31. -A gear-,nut '35 is engagedon the"A worm and held against' upward movement by .l a suitable caging 36. therearound .and formed integrally on the -extension 32, a stub shaft.

van secured by t e bolt 43,against lateral movement. I also include a'much longer side arm 48 fixed' with'relation'to the arm `47., and if desired formed inte ally'therewith, upon which suitable jacrs and sup- Cportlng vwheels may vbe mounted as .before-V escribed in connection'gwith the showing -It may bedesiredto sec `reth-eside pieces ofthe .frame in fixed parallel relation, so

thatthe device maybe used l.as anl ordinaryand inthis event, it may be found desirable to secure the caster members at the rearA end against swivel movement, for which purpose a pin 50 may be provided to be engaged through the pivot framing 0f lthe caster and with the wear plates-at the-head of the forks, as shown.

The device as before stated is adaptable 'l to construction in various sizes, and may be formed if desired 4withother styles of wheels than casters, this being suggested in Fig. 6,.where the frame is elevated at the forward part and mountedin 'any customary manner upon la two wheeled truck such as 1s customanly used 1n heavy wagon construction, and each' side member is provided with a heavy wheel 52 at its rear part. The intermediate flink 18 between the forward eliminated the heavier trucks, if, desired. f

used between the rear ends of lthe side members 0f the frame to form extensible connections,- and one method is suggested, which consists in securing a chain to the rear end ofone side, as at 54 in Fig. 1, extending the chain then to the end of the opposite side member and then forw-ardly within the channel iron on the outer side, a-hook beingprovided at the free end ofthe chain the side members on each side of the object and the foot piece 22 of the forward jack engaging beneath the object. The engagement of this foot piece lmay be greatly facilitated by withdrawing the pinch bar handle from the hollow shank 17 of the steering fork and raising the object therewith sufficiently to enable the foot piece 22 to pass thereunder. The forward jack is then operated to raise the object toa distance which will permit the foot pieces of the jack on the side members to `engage thereunder,

when the side members are moved inwardly pece ofthe fra-me and the side pieces mayl Any l suitable extensible means may be v for this purpose and the foot pieces of the respective jacks engaged under the object at each side. The rear ends of the side members are then connected to prevent their separation, and the rear jacksv operated. It may then be readily moved by securing the pinch bar in the steering forks. tially the same method may be pursued with any sizes of the truck when any object is to be raised. The truck is designed for usein moving general freight, pianos, heavy stone blocks, machinery, structural iron, and various other heavy or light materials.

It Will be apparent that the truck is extremely simple and inexpensive in construction, andV that it may be readily manipulated without diiiiculty. It will obviate the necessity for moving of extremely heavyv A considerable expenditure of time.

There is illustrated in Figs. 8, 9, and 10 an improved mounting of the jacks which it may be found desirable to use, and which consists in providing a base element 55, which may be either slidabl'eon the channel iron of the frame as shown at 57 or xed thereon as shown at 56. This base 1s formed with arms 58 extending upwardly and carrying a transverse shaft 59, upon which there is pivoted a heavy ear 60 formed at the back of a jack base 30', which may otherwise be constructed and equipped in the same way that the jack elements already described were. By this arrangement it can be seen that the jacks are adapted to be so inclined that they may engage objects having a considerable overhang, and they may be operated for hoisting in the same manner as the first described jacks, their inclination having no tendency to interfere with manipulation of the operating lever. In order to enable the jacks to be held in various inclined positions, a rack-toothed lever 61 is pivoted between suitable ears 62 on the back of the jack base 30', the lever being curved and provided with a finger-hold 63 at its outer end by which it may be lifted. The teeth are engageable with a tooth or lip 64 formed on the base 55A and projected upwardly. in suitable form for engagement with the teeth of the lever. The lever 61 is pivoted on the jack base a distance below the ear 60, so that the lower part of the jack will be supported in various positions by the Substanlever. The lever will fall by grai'fityintc') engagement with the tooth 64:.l In these views the foot 34 of the jack is provided with a pin or trunnion 65, so' that a chain 66 majT be engaged upon the pins of two opposed similar jacks, as shown in Fig. 10, enabling a pipe or other object with a great overhang at the sides to be transported.
